Mariah Carey, has, like, gone totally '80s — the singer is putting the finishing touches on the soundtrack to "All That Glitters," her upcoming flick based in the decade of Rubik's Cubes, big hair and acid-washed jeans.

The disc will be dominated by her vocals and music steeped in the sound of that era.

Though the film was originally expected as early as March, a representative for 20th Century Fox said Friday (February 2) that "All That Glitters" will not hit theaters until sometime in the second half of the year. The picture, which co-stars Da Brat and Eric Benét, wrapped shooting in October. It was filmed in Toronto and New York.

Carey collaborated with "Super Freak" singer Rick James and Jimmy Jam and Terry Lewis (Janet Jackson, Mary J. Blige) on the soundtrack, which also is expected to feature contributions by Da Brat and a duet between Carey and Benét.

"We tried to create the feel and the sonic landscape of the time, which was pretty easy for us to do, because in '81 we were in the Time and kind of starting that whole Minneapolis sound," Jimmy Jam said. "We actually pulled out a lot of old keyboards and drum machines we used back then. [Carey] said it would be cool to do something like the S.O.S. Band, so we pulled out the drum machine that we used for the S.O.S. Band records in the '80s. It's amazing, you plug that stuff up, and you're really, like, back there."

Jimmy Jam said Carey is "the quickest and most creative" artist he and Lewis have collaborated with. "Usually when we're with her, we don't have a lot of time. She'll fly into town for six hours and say, 'We have to write three songs.' "

Carey told MTV News in October that the soundtrack will also include a few covers, but she would not disclose which songs she's revisiting.

"All That Glitters" marks the first starring film role for the songstress, who had a small part in 1999's "The Bachelor." Carey, who plays an up-and-coming singer named Billie, is also producing the picture.
